Improve framerate

I’m trying to improve the framerate in my game, (this one) and I think I could use a little help. As the game is now, there are 400 block that are rigid body. When the game starts, it suspends dynamics so they don’t fall right away.
I tried making those blocks static and they spawn a rigid body block when shot. For some reason, it seems to have made the framerate even worse, if any change at all.
Does anyone have any tips on how I could make this more efficient?

If you remove the lights then the framerate goes up a lot. from 12 fps to 44 fps.

Yeah, I guess I do have too many lights. I’ll try baking some stuff. Thanks.
